Abstract
An infusion pump () includes a plunger () configured to squeeze a section of an infusion tube (). A proximal valve (), proximal to the plunger, ascends to allow infusion fluid intake from a reservoir to the infusion tube and descends to inhibit infusion fluid intake from the reservoir to the infusion tube. A distal valve (), distal to the plunger, ascends to allow infusion fluid flow past the distal valve, and descends to inhibit infusion fluid flow past the distal valve. A controller () controls the plunger, proximal valve, and distal valve by initiating descending of the plunger concurrently with or prior to the ascending of the distal valve, such that the descending of the plunger compensates for suction produced by the ascending of the distal valve, thereby reducing backflow of fluid from the subject. Other applications are also described.
